I don't know about "undercarriage" heating ... but our Winnebago motorhome has electrically heated grey water and black water tanks for traveling or camping in cold weather. Our fresh water tanks and all plumbing (except for the big 3 inch grey and black tank draining pipes) is in the heated interior of the motorhome.
I think that instead of electrically heated tanks, many motorhomes have the whole undercarriage around the grey and black water tanks heated. This means that you must have the furnace running long enough and high enough to be getting and keeping the undercarriage warm enough - including maybe even when going down the road in cold weather. Where in our situation when camping we only have to have a switch turned on to keep the tanks from freezing and the propane furnace on long enough and high enough to keep the interior warm enough for our personal comfort. When going down the road in freezing weather, we only need keep the tank heater switch on and the cab heater on.
